Stephane Peterhansel surged into the Dakar Rally lead on the 2013 event's first full-length stage as most of his main rivals hit trouble.
The 10-time winner's X-raid Mini was quickest by 2m35s over Giniel de Villiers' Toyota, giving Peterhansel a 2m38s overall advantage as the South African moved up to second.
Overnight leader Carlos Sainz was worst affected by a tricky dune 75 kilometers into the stage. Most chose to go around it, but Sainz was among those to attempt to tackle it directly and lost the course in the process. The former World Rally champion consequently lost 18 minutes and tumbled to 11th overall.
His Red Bull Buggy teammate Nasser Al-Attiyah fared little better in the dune and is now back to sixth place, 10 minutes down on Peterhansel.
Guerlain Chicherit was delayed by half an hour when his SMG Buggy sustained a puncture. But his team-mate Ronan Chabot is only eight seconds behind de Villiers in third.
Robby Gordon's so-far disastrous 2013 Dakar got worse as he lost a further 19 minutes to the leaders, leaving him 49 minutes adrift already in his Hummer.
